Modeling wise, exacto rolled off the bench and imbedded itself, blade deep, into the top of my right foot. Pulled it out, pinched it shut, a quick swipe with a rag, followed by a dab of CA....no blood on the carpet!
When I was around 10yrs old, I had a folding chair at my desk. I grabbed the seatback to scoot myself in toward the desk. When I scooted forward, the back legs started to fold up, enough room to get my right index finger in there. When I sat back down all the way, the rear legs folded back out, pinching off my finger tip.
A couple close calls in regular life. First one, I was on final approach, for a straight in landing at Sherman Field (Ft. Leavenworth KS.). I was right over the Mo. River, I saw a flock of geese approaching. They were high enough to not be a factor.....so I thought. One of em decided to kamakazee me. It dropped out of the flock, and nailed the top of the windscreen. It happened SO fast. When I openned my eyes, I had the right side control yoke right in my face! Only damage to the plane, surprizingly, was a crack in the windscreen, from the OAT guage to the top...5/6 inches. That was in a Cessna 150.
The other was in a 172. I had my daughter with me, about 6 at the time. We were flying over the lake we live at. Flying low (no less than 
500 agl
), following the tree line around the lake. There's an area with a sharp point out into the lake. I made a steep left turn, just like hundreds of times before! This time, the bottom dropped out. It felt like an elevator, heading toward the lake....azz first. There was just enough forward motion that I had very sluggish control. As the nose dropped, right aileron and full right rudder swung us around and back into full forward flight. We were less than ten feet from the water. My daughter enjoyed the ride.....I did not!!! Flew straight back to the airport and put the plane to bed...then I got the shakes.
